In a typical process, cellulosic biomasses, such as corn stover, sawgrass, or wood, is hydrolysed into glucose and other sugars using acid catalysts.
[9][10] However, due to blending limits for use in conventional combustion engines, it may be more efficient to convert GVL into liquid alkenes (or alkanes).
[11] After this stream is dehydrated, the products can be oligomerized at elevated pressures in the presence of a common acid-catalyst to yield alkenes with higher molecular weights, targeted for gasoline and other fuel applications.
[11] Apart from its value as a potential fuel in its own right, gamma-valerolactone has shown promise in laboratory-scale thermocatalytic production of soluble carbohydrates from corn stover and wood at high yields.
The gamma-valerolactone promotes thermocatalytic hydrolysis into monosaccharides by complete solubilization of the raw material, including lignins.
The saccharide products can be recovered from the lactone into water solution by antisolvent addition of salt or liquid carbon dioxide.
